The Kent Valley has some of the richest farmland in the world; but, being close to Seattle, it now hosts many rail and trucking facilities. So the painting is about the ratio of permeable park- and farmland to impermeable asphalt and concrete. The built portion of the landscape has gesso under it, which is, in it own way, an impermeable plastic coating; the rest is untreated, corresponding to the pervious nature of the un-built landscape.
